Under the watchful eye of their Mistress, two Graias' slaves, bound at the wrists, face each other. A whip is placed in each of their hands. The first girl tentatively brings the whip down, the leather kissing her companion's engorged pussy lips. The second girl returns the favor, her whip leaving a faint red mark on the first girl's clit. The Mistress, her voice dripping with desire, commands them to continue, their whips dancing between their thighs, their pussies aching for more than just the sting of the leather.
